Thisinventionrelates .to improvements in l cushion sockets, being particularly directed .to sockets wherein thevacuum tube support-- ed thereby may be positioned in a resiliently 5 supported floating base.

Oneof the inherent ,difliculties encountered in present day radio receptions isintroduced f in the use offixed sockets, dueto the fact 20 due-to the fact that it, the carrier, is fsuspended in a floating 'i "elationship with re spect tothe remainder Oftheelements, means, of a plurality of inter-acting flexible members.

, Broadly then, it is an vobjector thisiinven tion to pr vide for, a fiexible, socket. member in'which' afloating member, carrying the prongs, ofa vacuum tube associated therewith, may be displaced in a verticalland-horizont-al plane, ,with the.provision thatupon the attainmentofelement in either ofthe above said planes, the flexible .elementwill not of itself be overextended beyondits 11 1- mal movement range; bymeans of a posit ve Specifically, is thefaim of this invention toprov'ide for a flexible socket in which movement of a carri r, member composing" oneof .theelenie'nts therein, may be limited in i all planes, but which movement is sufiicient to] absorb any jars in, the said planes which may beimparted to the vacuum tube, car-i Figuresll and 12 riedtherein V a V Further, it, is an aim of this" invention to provide for afsocket member, which, being 1 composed of three intere'ng'aging" elements, maybe readily assembledbyany person,fin whiclndueto its ease 'of as'sembling', may be i applied, in all or in part, to afpanel memher within a radio circuit.

Still further, it is the aimofthis invention to provide for a flexible stamped conductor member, which serves as a resilient spring for maintaining the head of the socket in floating relationship with respect to the base ,thereof, and whichconductor member is adapted to carryva stop or. carrier member, disposed at the intermediate portion thereof, and

whicliconcluctor member is positively fixed atone end tothe basemember, and main? 3 ta nedin fixed position within, chambers formed in the head member by pressure, due to its tendency to expand.

F igure'9is a plan viewofa modifiedform Referring to" the referencecharacters in the drawing, numeral 20 represents an insuhtmgtase, to which the Wiring terminals: 7 are adaptedt'o be attached, the said baseuhaving, an; aperture 21 therein, within which aperture there is adapted, tO'bB positioned a coi'iductorlcarrying member 22. fThis con- I ductor carrying member comprises an insulating member having lateral extending carrier portions 23, in which apertures 24 are formed for the passage therethrough, for a flexible conductor member 25, to be later described.

This carrier or stop member 22 has a series of arms or vanes 26 formed integral with, and extending perpendicularly and horizontally from, the lateral arms, which arms have projecting portions 27 extending beyond the periphery of the aperture 21 within the in-.

sulating base 20, so that the movement of the carrier member is limited by the said projections, which form a stop due to the contact of the portions 27 with the periphery 21.

A series of terminals 28 are positioned along the outer periphery of said base member 20, which terminals are adapted to carry the conductor members 29, comprising the usual bolt and nut for inter-connection of this device with the remaining portions of the circuit. A series of insulating blocks 30 are formed along the under portion of the insulating member 20, being integral therewith, and serving to support the same in po sition.

Extending centrally and upwardly from the carrier member 22, there is formed a hub member 31, which hub member has a nut 32 positioned interiorly thereof, the said nut being adapted to cooperate with a screw member 33, passing through the head 34. The upper portion of the hub member 31 has a projection 35, which cooperates with an aperture 36, and the hub 37, of the head member 34, so that the head and the supporting member may be directly associated with one another for operation within the base member.

The head member 34, as shown in Figures 6 and 7, comprises a molded insulated memher, having a plurality of channels 38 therein, which channels terminate in one side in the form of a semi-circle as 39. This chamber 38, reaches to a point adjacent the top of the head member 34, and a circular opening 40 forms a continuation to the top of the head member. The screw member 33 is adapted to be positioned within the aperture 41, formed within the head member 34, and positioned so as to pass out of sight within the said aperture.

' Referring to Figures 4 to 9 inclusive, the contact members 42 are adapted to be formed of a single sheet of stamped metal, slidable through and within the apertures 24, and are shaped so that the portion 43, resting and in contact with the supporting member 22, is narrow. The conductor member is bent so that the extremity 44 is adapted to form a resilient pressure contact with a noncircular portion 45, of the chamber 38, while the main portion 45 is adapted to be positioned centrally of the aperture 40, adjacent the semicircular portion 39 within the chamber, so that prongs extending downwardly from a vacuum tube, contact directly with the face 45 of the conductor.

The bent-over portion 46is adapted to be positioned under the support member 22, after the conductor 42 has been positioned within the support, and the portion 46 drawn along and under the insulating base 20. The end extremity 47 of the conductor 42, is offset from the portion 46 thereof, so asto allow for added resiliency; the portion 47 being fixed to the insulating base 20 by means of a screw member 48.

Referring to Figures 9 and 10, a 1nodification is shown wherein the socket base is formed by a panel member 50, to the underside of which there are adapted to be fixed respective leads 51, by means of bolt members 52. The panel member 50 has an aperture centrally disposed therein, which aperture is attachable to the carrier member 53, through which the contact members of the same type as shown in Figure 8 are adapted The head member 54 is to be supported. similar in structural detail to that shown in Figure 7.

Referring to Figures 11, 12, and 13, a modified form is shown wherein the cushioning effect is not provided for. structure a molded head is attachable to the base 61 by means of the screw 62, to which the bolt 63, at the underpart of the base 61, is attachable. The conducting prongs 64 comprise a bent stamping, the head 65 of which is adapted to fit into the chamber of the same type as that shown in Figure 7 within the head member 34. The extremity 66 of said stamping extends perpendicularly from the base 61, as shown in Figure 13, is bent over in actual operation for fastening to the remaining elements in the circuit.

' It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.

1 7 What I claim is 1. In a device of the class described, the combination with a suporting member, contact terminals on said supporting member, a head member having apertures therein for the passage of prongs therethrough, and flexible conductor members, having one extremity positioned within said head member, and the other extremity fastened to the contact terminals on said supporting member, said head member being thereby floatingly supported with respect to the supporting memher, and means attachable to said head member, and through which said flexible conductor members pass, for limiting the movement of the head member with respect to the supporting member.

In this type of 2. In a device of the class described, a base member, ahead member cooperating there with, chambers within said head member,

conductor members fixed to said base memher, and extending upwardly and inwardly and resting within the chambers insaid head member, said conductor members being adapted to be locked within said head memher by pressure contact whereby the head member may be supported in floating relationship with respect to the base member, and means comprlsmg an msulatlng member 7 attachable to said head member, and having apertures therein for the passage therethrough, and the retention of said conductor members, whereby to limit the floating movement of said headmember.
